DHL Mechanical - Boiler Expert

We’ve used Mark and DHL for a number of years for routine maintenance and he was our first call when the whole system was ready for replacement (2 furnaces + A/C). The mech room in our 1960’s home is very tight and Mark and his team solved it like a puzzle; replacing the jumble of older equipment with a modern “wall of machinery”. This job spanned all the trades; HVAC, plumbing, electrical, and even some woodworking to create a custom cold air return cover on our main floor. The team put down lots of protective material on the flooring, cleaned up after every day’s work, is very respectful of not damaging your home and left everything completely clean. When you want something done well, DHL is highly recommended for complex projects such as this.

All that needs to be said is that I did my homework before engaging DHL Mechanical for my project and I was very pleased with the outcomes. I am happy to give a reference. The pictures tell the story.

We cannot say enough about the excellent service and expertise we received from Mark and his team at DHL Mechanical. After an extensive review of our current system he was thoughtful and thorough with his evaluation of how we could be improving the water service throughout our home. After an emergency call, we received prompt and efficient care as well. We are tremendously happy with our new system and are thankful with the care and attention we received to ensure we understood what was being installed as well as how to most effectively maintain it for years to come. Thank you!

Mark and his team have been doing work for me since 2018. It took me a while to find a team that actually understands boilers and hydronic heating systems, and DHL is it. They've done great work maintaining my system and recently installing a new condensing, high efficiency boiler. They do great work - very professional, respectful of your home, neat and tidy, friendly and pleasant, and always happy to explain what needs done and why. Highly recommended.

DHL responded in the dead of winter to replace an old low efficiency boiler that failed with a new high efficiency IBC system. Not only did they do amazing work (see the photo), but their attention to detail was so strong that they went around and fixed and brought up to code a bunch of errors that a local big-name company did when that competitor installed a new furnace years ago. Mark and his sons and staff are amazing!

DHL Mechanical (Mark Davie) is not only a true expert with boilers and hydronic/piping systems, but he is also perfectionist, and extremely meticulous from the time he enters your home, to when he has completed the job. Even better yet, he is very honest, and is amazing at promptly responding to service calls and backing up his work.The nice thing about DHL is the person you talk to on the phone when you call is the person overseeing the work. DHL's knowledge an know-how can competently complete small and large jobs of any type. You know he's the right guy when other contractors see his work and stop to admire it.

I had Mark from DHL come & replace my 60 yr old boiler. He was the only quote I got but felt totally confident that he would get the job done right. He was on time every single day & the worksite was cleaned up before he left. He kept me informed of the progress every step of the way. I have recommended DHL in the past & will continue to do so.

Professional, honest, respectful! I highly recommend! They took extreme care to protect my home. They worked as a team and I barely knew they were there. Easy to communicate with and I will be calling them for all of our mechanical needs from now on.

Mark and his team replaced my ancient boiler with a new one, and the whole event was so smooth. They communicated with us at all stages, walking us through what changes they made and why. I now have a better understanding of how the system works, and can do the maintenance myself. Highly recommend!

We have been customers of DHL for several years and have not had one bad experience. We highly recommend DHL Mechanical. Mark and his son transformed our mechanical room (avoiding near disaster because of how the builder installed our boiler) to an efficient, organized, highly functional space. Mark is always responsive and during the last cold snap responded quickly to replace the original air handler that failed and left our upstairs without heat. The new unit has made a great improvement for the overall heat distribution in the colder rooms.
